Question

 An archaeological team is excavating artifacts from a sunken merchant vessel on the ocean floor. To help with the exploration, the team uses a robotic probe. The probe travels approximately 4,800 meters at an angle of depression of 69.3° from the team’s ship on the ocean surface down to the sunken vessel on the ocean floor. 

a.   When the probe reaches the ocean floor, how far will it be below the ocean surface?

b.   When the probe reaches the ocean floor, what will be the horizontal distance between the ship and the probe?

c.   If the probe travels horizontally at a speed of 5 meters per second, how long will it take for the probe to be underneath the ship?

Answer 1

Distance from the ocean surface to bottom, (cos 69.3)(4800 m) = 1696.9 m.

Horizontal distance from the ship to the probe, (sin 69.3)(4800 m) = 4490 m.
